It absorbs minor bumps during cornering, eliminating vibrations that interfere with the rider.\u003cbr\u003e\n ●Unlike regular springs, there is no fixed spring rate, so there is no resonance.\u003cbr\u003e\n ●Springs wound by computer-controlled machine tools are shot-peened to remove microscopic surface scratches that can lead to performance degradation. Furthermore, after completion, each spring undergoes performance inspection by a tester.\u003cbr\u003e\n ●In Hyperpro's home country of the Netherlands, all ambulance motorcycles are equipped with Hyperpro springs.\u003cbr\u003e\n Compatible models\u003cbr\u003e\n YAMAHA YZF-R1 '07-'08\u003cbr\u003e\n Specifications\u003cbr\u003e\n Spring Part Number: 1144\u003cbr\u003e\n Fork Oil Viscosity\/Oil Level: SAE7.5\/135mm\u003cbr\u003e\n Preload Adjustment: 3-4 clicks\u003cbr\u003e\n Sag Value: 24mm\u003cbr\u003e\n Compression Adjustment: 15 +\/- 5 clicks out\u003cbr\u003e\n Rebound Adjustment: 8 +\/- 4 clicks out\u003cbr\u003e\n Setting Remarks: Install with the tapered end up\u003cbr\u003e\n *Images are for illustration purposes only, and the design and specifications of the products shown are subject to change without notice.
